Answer:

112

Step-by-step explanation:

This is a cyclic quadralterial. A cyclic quadralterial is a quadralterial that is inscribed in a circle where all the point or vertices of the quadralterial touches the circle circumference. Opposite angles in a cyclic quadralterial are supplementary.

Angle R and Angle QPS or P is supplementary since they are opposite angle.

Substitute 68 for R

$68 + qps = 180$

$qps = 112$

So the answer is 112

10x(x - 5) = 0

10x = 0
x = 0 <== this one is eliminated because x cannot be zero

x - 5 = 0
x = 5 <== ur answer
